mysqlが起動しない：binファイルのエラー13（権限が正しく設定されている）
ホスト名を変更してサーバーを再起動したところ、mysql 5.6が起動しなくなりました。 （debian 7 + dotdeb）
150312 20:40:15 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql.mnt
2015-03-12 20:40:15 13855 [Warning] Buffered warning: Changed limits: max_open_files: 1024 (requested 5000)

^G/usr/sbin/mysqld: File '/var/export/websrvDB.log/websrvDB-bin.index' not found (Errcode: 13 - Permission denied)
2015-03-12 20:40:15 13855 [ERROR] Aborting

2015-03-12 20:40:15 13855 [Note] /usr/sbin/mysqld: Shutdown complete
しかし、それは意味がありません
/var/export/websrvDB.logにはmysql：mysql 700があり、そこにあるすべてのファイルには600とmysql：mysqlがあります
他のすべての所有権も正常に見え、binlogをオフにするとサーバーが起動します。
ログフォルダにはかなりのGBのファイルが134個あります。 .indexファイルには、すべて正しく含まれているようです。ログファイルの^ Gにも戸惑い、毎回表示されます。
誰か助けてくれてありがとう、ありがとう。

個人的に、私はあなたが持っている許可にそれほど満足していません。
Mysqldが実行されていないので、以下を試してください
cd /var/export/websrvDB.log
mkdir junk
cd junk
mv ../websrvDB-bin.* .
cd ..
service mysql start
ls -l websrvDB-bin.*
mysqldが起動し、新しいバイナリログとインデックスファイルを作成します。 websrvDB-bin.000001およびwebsrvDB-bin.indexの権限を確認してください。これらは正しい権限であるはずです。
あなたもこれをするべきです
chmod -R 644 /var/export/websrvDB.log
mySQLを再起動してみてください
このサーバーで何が起こっているのかはわかりませんが、問題はopenVZに関連しています。
何らかの理由で、サーバーは、マウントされているフォルダーにバイナリログを保存したくないと判断しました。まだこれを解決しようとしています。
